Steel frame system SFS - Infill walling:

SFS ‘steel framing system’ infill walling represents our most economical framing method. It is constructed from the floor to soffit of the primary structural frame to ‘infill’ the external wall zone.

Overview of the SFS Infill Walling System:

Metsec SFS infill walling forms a secondary structure which is fixed between the primary super structure at floor and soffit. The steel frame system is generally positioned at the slab edge allowing insulation and external finishes to be installed continuously outside the main structural frame.

Parapets and Downstands:

SFS systems can incorporate parapets and downstands, which can readily be formed with SFS using Metsec’s cantilever posts, which can be incorporated within the Metsec steel framing system. These posts can also be used to break up the span of wide openings and allow the formation of ribbon windows.

Compound Sections:

In SFS steel framing systems where it is necessary to use sections with a higher capacity, single sections can be fixed together to form compound sections. This can be done for jamb, cill and lintel sections.

Infill Wall Sections Explained:

voestalpine Metsec SFS infill solution section references are designed to be easy to read and understand at a glance. Each section type is identified by a unique reference consisting of three numerical values separated by a letter or a dash unique to the voestalpines Metsec SFS Steel Framing Systems

Studs Sections explained:

Example stud reference – 090M12-50

• • 090 – Refers to the section depth of 90mm (numbers ending in 0 are always lipped)
  • M – Refers to Metsec SFS
  • 12 – Refers to the gauge (thickness) of the section i.e. 12 is 1.2mm thick
  • 50 – Refers to the width or section flange of 50mm
